Beware that printer access may be restricted based on the requesting IP address. See:

CIDR Notation is used to specify the allowed IP address ranges.

12.6.1. CIDR Notation

Classless Inter-Domain Routing (CIDR) is developed in the 1990s as a standard scheme for routing network traffic across the Internet.

CIDR notation is a syntax for specifying IP addresses and their associated prefix size, the latter being equivalent to the number of leading 1 bits in the routing prefix mask. The notation starts with an IP address expressed according to the standards of IPv4 or IPv6. It is followed by a separator character, the slash (/) character, and the prefix size expressed as a decimal number.

Some examples:

  • represents the given IPv4 address and its associated routing prefix, or equivalently, its subnet mask This represents the host address range -

  • CIDR represents the single IP address

12.6.2. CIDR Set

For SavaPage use only we define a CIDR Set as a concatenation of single CIDR notations separated by any of the characters space, comma, colon or semicolon.
